This sample is a .NET (MSIL) AsyncRAT trojan disguised as a legitimate application. VirusTotal reports that a majority of security vendors classify it as AsyncRAT / MSIL backdoor. Static analysis indicates heavy obfuscation, anti-analysis / anti-debugging checks, and long sleep delays to evade sandbox detection. Behavioral analysis and Sigma rule matches suggest persistence via scheduled task creation (schtasks.exe), execution from suspicious paths or environment variables, and network communication over uncommon destination ports. Sandbox results classify the file as a remote access trojan (RAT) with evasion capabilities, consistent with known AsyncRAT tradecraft. This sample is suitable for malware research, detection engineering, and threat intelligence correlation.
